Cartography is data combined with the generic styling rules. Since the rendered tiles are therefore subject to the style license (think of icons, patterns etc. for example) as well as the data license the CC-By-SA makes a lot of sense since it implicitly includes the ODbL attribution requirements. Most other licenses for the tiles would require a special clause for that. The style itself however does not require attribution when used with non-OSM data since it is CC0. You can still render tiles using the standard style and OSM data yourself and distribute them under something other than CC-By-SA as long as you comply with the ODbL. But if you use those rendered by the OSMF servers they are CC-By-SA. -- Christoph Hormann http://www.imagico.de/ _______________________________________________ legal-talk mailing list [email protected] https://lists.openstreetmap.org/listinfo/legal-talk
